Why would that be a problem? Why would something being related to or pursuant to a value judgement be barred from being a fact? Cant a value judgement be based on a measurement? Aren't all measurements based in standards?
A measurement is independent upon my reading, someone else can make a measurement and come to the same measurement as I've measured. Not so for value judgements, my red cannot ever be your red. My "murder is wrong" isn't a measurement in the same sense as something being "red", at least, I think so.
I'm unsure as to what facts can be said on morality, still. It seems to me you have a tenuous and/or broad definition of "facts". For me a fact would be something like "there are 8 planets in the Solar system" or "the radius of Earth is 6,371 km", something that is not a fact would be "the sky is blue", what is blue in this context? How do you define "blue"? Facts are objective truths while something like "the sky is blue" is subjective, while in the adverse the "light scattering of the atmosphere is ~490–450 nm" which of course is what most people probably experience the color blue. That is an example of the difference between a fact and something like an opinion.
